Definitions

  • the fibers obtained by this method are stable fibers, have a branched structure, and may have a loop and Z or crimp.
  • the web is compressed while being heated to a temperature equal to or higher than the melting point of the hot-melt resin. Heating can be done through hot air. Compression can be performed on the bottom of the tube with a plate or belt, or with a mouthpiece. The amount of compression is usually controlled by controlling the compression allowance at the limit gauge. In this way, thermal bond nonwoven fabrics cannot be manufactured.
